US airline stocks closed significantly higher on Tuesday after Spirit Airlines, a budget air carrier , issued a dire warning that it will fail to survive as a going concern without fresh capital.

Additionally, the US Labor Department reported an increase in July airfares (the first in six months), further injecting fuel to the airline stocks rally on Tuesday.  

Airline stocks have been a lucrative investment over the past four months.

At the time of writing, “JETS” – an exchange-traded fund (ETF) that tracks the global airline industry is up more than 50% versus its April low.  

Why is Spirit Airlines’ bankruptcy a positive for airline stocks?

If Spirit Airlines fails to raise new capital and ends up in bankruptcy again, it could be a net positive for the rest of the airline industry.

Why? Because Spirit’s ultra-low-cost model has long pressured fares across the board, especially in leisure-heavy domestic routes.

Its exit would reduce excess capacity, allowing legacy carriers like Delta, United, and American Airlines to regain pricing power and improve load factors.

Fewer seats chasing the same demand means better margins and less need for aggressive discounting.

In short, Spirit’s potential collapse could help restore balance to a market that’s been oversaturated and margin-thin for months.

That’s what made airline stocks, including DAL, UAL, and AAL push meaningfully to the upside on Tuesday.

Why else are airline stocks rallying today?

US airline stocks ripped higher on August 12th, also because the recorded uptick in monthly airfares signals a turning point for the airline industry.

After months of fare declines driven by soft demand and overcapacity, July data suggests carriers are successfully trimming supply to match demand.

That’s a bullish sign for profitability. Rising ticket prices indicate that airlines are regaining control over pricing, which is crucial for margin recovery.

Investors are responding to this shift, viewing it as evidence that the worst of the pricing pressure may now be in the rearview mirror.

Together with disciplined capacity management, it paints a more optimistic picture for the sector and what the future holds for air lines stock heading into fall 2025.

Is there no hope left for Spirit Airlines stock?

Regardless of whether Spirit Airlines succeeds in raising fresh capital or not, FLYY shares are full of risk and, therefore, a no-go for the second half of 2025.

If the air carrier fails to secure new funding, bankruptcy is on the table, which may wipe out shareholders.

However, even if it does raise cash, it will likely come at a significant discount, diluting existing investors.

All in all, the budget airlines financials remain weak, and it’s restructuring didn’t deliver the turn-around investors had hoped for.

With mounting losses, pilot furloughs, and a challenging pricing environment, Spirit Airlines stock offers little upside and severe risk of further downside.

Spirit may be flying for now – but its stock sure is grounded already.
